A series of 2-benzylthiopyridine-4-carbonitriles 4 and a series of 2- benzylthiopyridine-4-carbothioamides 5 were prepared. Their chemical structures were proved by IR and 1H NMR data and by elemental analysis. The MIC assessment was used for the estimation of their potential antimycobacterial and antifungal activity in vitro. The compounds were shown to be more active against mycobacterial strains than the tested fungi. Their antimycobacterial activity appears to be related mainly to the benzylthio moiety, while the antifungal activity appears to be related to the carbothioamide group. Substituents on the benzylthio moiety of derivatives 5 modified antifungal activity, whereas they did not play any significant role in antimycobacterial activity. The inhibiting effect of 4 and 5 on the photochemical activity of spinach chloroplasts was determined by IC50 values. The compounds exhibited a moderate photosynthesis-inhibiting activity.
Promoting Effect of Crystal Water Leading to Catalyst-Free Synthesis of Heteroaryl Thioether from Heteroaryl Chloride, Sodium Thiosulfate Pentahydrate, and Alcohol

It is observed the crystal water in sodium thiosulfate pentahydrate (Na2S2O3·5H2O) can promote its multicomponent reaction with heteroaryl chlorides and alcohols, providing a facile, green, and specific synthesis of unsymmetrical heteroaryl thioethers via one-step formation of two C-S bonds under catalyst-, additive-, and solvent-free conditions. Mechanistic studies suggest that the crystal water in Na2S2O3·5H2O is crucial in generating the key thiol intermediates and byproduct NaHSO4, which then catalyzes the dehydrative substitution of alcohols with thiols to afford thioethers.
